"plasmonic titanium nitride and aluminum-doped zinc oxide... can control the materials' optical properties, most notably epsilon near zero behaviors... lowest reported optical losses, providing novel applications for telecommunications and furthers study of optical nonlinearities... controlling the ENZ point, the wavelength at which a material is neither dielectric nor metallic... thickness association of optical properties easy to manipulate, enabling growth of films with different ENZ properties"
